Which of the majority 4 Conservative committee members are you suggesting are Remainers?
Costa appears to be the only one who was anti Brexit pre 2016.
Of the four Conservatives on the committee, three voted a while ago to do nothing about Owen Paterson (remember him?) and the fourth abstained. The chances of them finding the PM guilty of any wrongdoing, regardless of the evidence, is, er, assessed as somewhat close to zero. From the Number Ten point of view, they are a pretty safe bet.
